Call the theorem prover's simplifier, creating a subgoal for each
resulting goal.

Notice that unlike prove, the arguments to bash are spread out, and
are all hints.

Bash is similar to reduce in that neither of these allows induction.
But bash only allows simplification, while reduce allows processes
eliminate-destructors, fertilize, generalize, and
eliminate-irrelevance.

Note: All forcing rounds will be skipped (unless there are more
than 15 subgoals generated in the first forcing round, an injustice
that should be rectified by the next release).
